Genital issues


Recently, I noticed a small red bump at the junction of the penis (near the pubic hair).
Could this be a sexually transmitted infection? However, I haven't had sexual intercourse for over six years.
Could it simply be folliculitis? Thank you for your response, doctor.

Hello: Keep the area clean and dry.
If it is folliculitis, it will mostly improve; if it does not improve, you should seek medical attention.
Wishing you good health.

More Info


When it comes to red bumps on the penis, it is essential to consider various possibilities, including folliculitis, sexually transmitted infections (STIs), or other dermatological conditions. Given your history of not engaging in sexual activity for over six years, the likelihood of an STI may be lower, but it is not entirely ruled out, especially if there have been any recent changes in your sexual health or exposure to new partners.

Folliculitis is a common condition that occurs when hair follicles become inflamed, often due to bacterial or fungal infections. This can result in small red bumps or pustules that may resemble acne. Folliculitis can occur anywhere on the body where hair follicles are present, including the genital area. Factors that contribute to folliculitis include shaving, friction from clothing, or excessive sweating. If the bump is tender, itchy, or surrounded by redness, it may indicate an infection.

On the other hand, sexually transmitted infections can also present with red bumps or lesions on the genital area. Common STIs like herpes or genital warts can cause similar symptoms. Herpes typically presents as painful blisters or sores, while genital warts appear as small, flesh-colored or red bumps that can cluster together. However, given your stated lack of sexual activity, the risk of these infections is likely reduced.

Other potential causes for red bumps in the genital area include:
1. Pearly Penile Papules: These are small, harmless bumps that can appear around the corona of the glans (the head of the penis). They are normal anatomical variations and are not associated with any disease.

2. Fordyce Spots: These are small, painless, pale bumps that are sebaceous glands without hair follicles. They are also harmless and common.

3. Contact Dermatitis: This can occur due to irritation from soaps, lotions, or other products that come into contact with the skin. It may cause redness, itching, and bumps.

4. Lichen Planus: This is an inflammatory condition that can affect the skin and mucous membranes, leading to purplish, itchy bumps.

5. Cysts: Sebaceous cysts can form in the genital area and may appear as small, firm bumps.

Given the variety of potential causes, it is crucial to observe the bump's characteristics. If the bump is persistent, changing in appearance, or accompanied by other symptoms such as pain, itching, or discharge, it is advisable to seek medical attention. A healthcare provider can perform a physical examination and may recommend tests or treatments based on the diagnosis.

In summary, while folliculitis is a likely cause of the red bump you are experiencing, it is essential to consider other possibilities. If you have any concerns about STIs or if the bump does not resolve, consulting a healthcare professional is the best course of action. They can provide a thorough evaluation and appropriate management to ensure your health and peace of mind.
